Time intervals for global transmission of each variant of concern of SARS-CoV-2 from May 2020 to November 2022. Biweekly aggregated numbers of the proportions of variants were retrieved from CoVariants.org for 58 locations, selected due to their (highest) total reported cases of SARS-CoV-2. The times when each variant exceeded 60% of all samples sequenced in a location are shown using coloured bars. Locations are ranked and presented according to their longitude from east (top) to west (bottom).
